Boost Your Home's Warmth & Energy Efficiency

This PET Aluminized Thermal Insulation Film is a smart, cost-effective way to maximize your radiator's performance. By reflecting up to 90% of radiated heat back into your room, this reflective film prevents energy loss through cold walls — helping your space feel warmer without turning up the thermostat. Made in Mainland China.

Key Features

• 💰 Save on Energy Bills: Installed behind your radiator, this film redirects heat that would otherwise be absorbed by the wall — increasing room temperature efficiency and potentially lowering heating costs.
• 🔄 Multi-Purpose Design: Suitable for all standard radiator models and a wide variety of thermal insulation applications, including containers and wall installations. Universally compatible.
• 🛠️ Easy to Install: Simply cut to size and attach behind your radiator using double-sided tape (sold separately). No special tools or expertise needed — a quick DIY upgrade anyone can do.
• 🏗️ Quality Construction: Made from PET aluminized film laminated over pearl cotton foam polyethylene, with a 3mm thickness for durability and effective thermal performance.
• 🌡️ High Reflectivity: The aluminized surface reflects radiant heat efficiently, channeling warmth toward the interior of your room rather than losing it through the wall.
